Device internal data preparation and migration

Abstract

This application is directed to preparing and processing data locally in a memory system that includes a data processor, a memory controller, and a non-volatile memory (e.g., NAND flash memory). The memory system obtaining a request for processing first data. A modified form of the first data has been stored as second data in the non-volatile memory. The memory system identifies the second data stored in the non-volatile memory, and extracts the second data from the non-volatile memory. The second data is processed by the memory controller of the memory system to recover the first data, which are further provided to the data processor for processing locally within the memory system. In some embodiments, the memory controller temporarily stores the second data in a first memory and the recovered first data in a second memory from which the data processor extracts the recovered first data for further local on-memory processing.
